While I do not understand above (does the mp4 contain duplicate 
frames, or MEncoder duplicates frames when re-encoding? Do you 
actually want to re-encode or do you want to extract audio? If 
you want to extract audio, why do you re-encode?), I suspect 
ffmpeg should be able to both extract audio and re-encode your 
input file.

Note that MEncoder is not an actively maintained application 
for several years, FFmpeg is.
